APPARATUS FOR INDICATING AND CHECKING SUPPLY OF BEER, &c., IN GLASSES,TANKARDS, de.

SPECIFICATION forming part of Letters Patent N0. 649,581, dated May 15,1900.

Application filed J'une 21, 1897.

.To all whom t may concern.-

Be it known that I, LOUIS BEYER, manufacturer, of Giebichenstein, nearHalle, in the Kingdom of Prussia, German Empire, have invented new anduseful Improvements in Apparatus for Indicating and Checking the Supplyof Beer or other Liquors in Glasses, Tankards, or the Like, of which thefollowing is a specification.

This invention relates to a device for' indicating and checking thenumber of glasses of beer or other liquor supplied to a customer,whereby any fraud on the part of the waiter or the customer isprevented.

The said device is contained Within the stand on which the beer-glass,tankard, or other drinking vessel is placed before the customer.

The invention is illustrated in the accompanying drawings. A

Figure l is a side view of the stand for the beer-glass, with thechecking mechanism contained therein shown in dotted lines. Fig. 2 is aplan view of such stand; Fig. 3, a crosssection of the same; Fig. 4L,another side view Fig. 5, a partial plan; Fig. 6, a modification of thestand, and Fig. 7 a mark or token in plan and side view.

The stand for the beer-glass consists of an upper part A and a lowerpart B, which are correspondingly shaped and iirmly connected together.In the center of the lower part B a pin n is fixed, and to this pin aspring b is attached, which constantly bears on the part a' of ametal'counting-band or indicating-ribbon d, running in the groove Z. Theupper part A of the stand is provided with a slot o, furnished with aspring-cover 7i. Vhen a glass of beer, for example, is delivered tothecustomer, a token or counter a, Fig. 7, is placed in the slot o andextends into the groove Z, pushing the abovementioned countingband orindicating-ribbon a certain distance forward. rIhe indicating-ribbon isfurnished with numbers, one of which is constantly visible through theaperture g, Fig. 1. ing the apparatus to be set at zero and a mark orcounter is inserted, the latter will push the indicating-band sov far asto cause the numeral l to be visible through the aperture g. This actionwill be repeated every time a glass of beer is delivered to thecustomer, so that the number of glasses delivered can be visi` bly andaccurately noted.

Suppos- Serial No. 641,680. (No model.)

For the purpose of preventing any fraudthat is to say, renderingimpossible any unauthorized tampering with the indicatingband-the latteris provided on its upper edge with teeth or indentations, in which apawl c is pressed bya spring d. In order to remove the counters ortokens from the apparatus, the flap c', which is hinged at 7c, should beunfastened from the under part B of the stand and folded back. Theratchet-pawl c is now released, and thc spring b,'which engages with theindicating-ribbon a at a', will push all the tokens or counters towardand allow them to fall out through the aperture produced by the turningback of the iiap t'.

If the tokens are to be used as beer-tokens--` that is to say, in payingfor the beer-the apparatus is arranged to operate in a manner exactlythe reverse of the above and is charged with a number of the tokensbefore the first glass of beer is delivered to the customer and thespring b thereby putin tension. When the waiter delivers a glass ofbeer, he takes away one of the counters e, Fig. G, projecting from theopening o, (the springcover h not being used in this case,) whereby thespring b causes the indicating-band a to move forward and a numbercorresponding with the number of glasses supplied appears through theaperture g.

Having now described my invention, what I claim, and desire to secure byLetters Patent, is-Vm l An apparatus for indicating the number ofglasses supplied to customers comprising the stand or support for theglasses having an annular channel and a compartment beneathcommunicating with said channel, said channel having an exposing-openingin its side, the band set on edge in the channel and bearing indicatingcharacters, the spring supported at one end centrally of the compartmentand having its opposite end engaging a projection of the band, saidchannel having an opening to receive counters adapted to move the band,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

LOUIS BEYER.
